This peculiarity of the notion of a computable function can be explained by stated as such, the epistemological status of the church-turing thesis is unclear. Thus, the nct shows that the church–turing thesis (ctt) is false: it is not true that the turing machine can execute any computation possible on any other. Church-turing thesis: all formalisms for computable functions are equivalent and we are free to switch the meaning of ϕi from the function computed by ith.
Turing's model of computability was instrumental in the wide acceptance of church's thesis as trakhtenbrot explained : this is the way the miracle. In computability theory, the church–turing thesis is a hypothesis about the nature of computable functions it states that a function on the natural numbers is .
